Be it lniown that il., JAMES O. Srliimn'r, n citi/:en o'l the United States, and u resident ot Spokane, in the county of Spokane Iand Stute oi Washington7 have invented n.' ne.` and ln'iproved 'i`i1'e-t5prending Device, of which the following is n full, clear, and eX ziet description.

This invention relates to iinproven'ients in tire-spreading devicee und hes for :in ohject to provide an improved structure for spreading n clencher tire structure so as to permit ready` inspection of the vinterior thereof.

Another object of the invention to pro vide n sprezufiinp; device for tires Whiehinny he quickly and easily operated :and which `will securely spread the tire without any injur/ thereto. so as to disclose the interior :e or fece.

ln carrying ont the objects ofthe inlVention7 n vtehle structure of any desired hind may he used 'with nn opening' therein through which n pair of tong` structures are projected, the tong structures being pivotailly connected below the top oi the table :ind held supported by one or more springs. IThe lower ends of the tong structures `are lient: outwardlyv or away from each other so thatJ when moved together the opper ends ot the 'pzirtsoi" the tongs will be selen-ated. A trendle structure is connected with these out\vercllybent ends so es to allow n. quick opening,` of the jews or points of `the tongs when n tire is engaged thereby so :is to quickly openior inspection of a tire.

A. prztctienl embodiment of the invention is represented in the accompanying drow-- ings. in which encev indicate corresponding parts in ail the views.

Figure 'l is :1. side elevation oi' n table and pair of tongs and associateddevices emhodying the features of the invention, n fragment 03F the tire being shown. in 'connection therei'vth; Fig; 2 is e sideview' of the structure shown in Fig. It breiten, einer to readily di and S discloses n fragmentar/ View et ible' and associated devices emhodjying e slightly modified forni ot" the invention.

'eferring to the drawings by nnmernls,`1 indicates e table,a of :my desired kind, here@ ing e suitable top* 2 end herring e treedle 3 j iiv'etelly connected therewith.. preferably similar characters of reifen' the 'table beiiiiigw sctose the pnrts'g near the hott in thereof. The ton 2 isprovided with 21. slot Lletlirongh which is projected vthe jaws 5 and 6 of a pair merging to overhunging hooks or and 8 dei'gned to hook over the edges of n tire SL :is eleurly shown in Fie. l. Neer their lower ends the jews 5 and G ere pivotnlly connected together by n suitable pin l() which also carries springe l1 and 1Q., The springs 'll and .l2 are eonneted hy any -d ineens, es, for instance, i staple 'to the tnhle l, or to suitable reinforcing ioeinf here li :ind connected with the top et the tnhle, of; shown in Fie'. Q. The lower ends of the jews und ti :ire not crossed but. cui-red ontufznfdly ttor providing urine. 1G :ind l''". "heee nrnis nre eonneeted hy any desired forni oit ilexihle n'ien'iher tor instance, :i Chain .ttl which hes n. hook lt* een nected with the center thereof, preferably hy heine; hooked into a. link 2() mounted upon the central linhn ol Vthe chain. although,

1 9 could he directly iit' desired, the hook hooked to the control link of the chain. The pi'votally of tongs2 points 1 bottoni of the hook or rod 1.9 is eonneeted with the trendle the treudle is; depressed by the :toot or other ineens the chain 18 will he pulled downwzndly at its center point and thus conse the enter ende of the :mns lo' :ind 1T to approach euch other. This will cnn-se the pointe` "i :i nd 5% to s vnend, is shown in dotted lines,` in Fig. 1t and eonsequently t0 eprend e tire it the seine ie connected therewith. In

this wey the tire ,may he quickly ond easily inspected und maintained open'or any desii'ed length of time with n mininiuinieitoit.

ln large :intoniohile tires it is well, knon'ii that the seine ere very stili and hard to open for inspection. By arranging the jews 5 Lnid G, the treedl. 8 and associated parts es described., ineens, are presentedwiiieh will quickly and easily open :i tire for inspeetion or repairs.

l.lt'hen it; is desired te insert a tire into the jaws t.; und 6', the same only be easily r-inspired :ind moved :rpm-t, :ind then hooked e es shown in ull lines in i. to maintain. the tire in open posi te considerable time, the trendle ongle iron, and 'Whiclris eenght beneath 'the teeth of o. 3*9 lll/when the treedle 3 1olly the seme is, 0i' eonrse,

3 so that when with e eoteh 21, formed sull! titi 'Hit

lie

moved against the acion of the springs l1 and l2 as Weil as againsty the tire 9. In this ay means are provided for positively returning the jaws to their former position regardless of the action o the tir Qccnsionally small tires are desired to be inspected, and when inspecting tires of this variety a bloei: 23 is preferably arranged on the table, as shown in the modified form in Fig. 3. ln this Way the 'nire 25 though smaller than the tire Sais opened in. a similar manner and, may be held open by causing :he niembervQl to engage the raolr 2Q.

Having thus described my invention, I claim as newand desire to secure by Let-ters Patent:
